We're dividing 67783 by 90 
The aim is to understand the frequency of 90 in 67783.

Moving on to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 90

Let's proceed to step 2:
The number 90 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 90

On to step 3:
When dividing 677 by 90, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 630 from 677 and we're left with 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 90

Let's proceed to step 4:
If we divide 478 by 90, we get 5 and a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 450 from 478 to get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 90

On to step 5:
90 goes into 283 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 753.0
Subtract 270 from 283 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
90 goes into 130 1 times with a remainder of 40.
The next digit of our result is 1. 
Result so far: 753.1
The remainder is 40 after subtracting 90 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
90 goes into 400 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 753.14
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 90 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 753.144
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 753.144, and the remainder is 0.004.
